Thats not entirely accurate. Ufraw has for a long time included a batch tool called ufraw-batch. Try running that command it if you have ufraw installed and see for yourself. The idea is that you process one image in the series in the normal ufraw gui and save the changes you made as a template to a config file (thats what that button in the ufraw gui is for). Then you have ufraw-batch load that config and process as many pictures as you like. I tried rawstudio, but it kept crashing for me. Been using ufraw for two years, and it works great here. I don't think the UI is confusing.
Its command-line only, thats probably why you missed.
